Resin Button Production Process

- Dec 08, 2017-

(1) Unsaturated Polyester Resin The resin used for producing buttons needs to have a viscosity of 10-20 Pa.s, low heat release during curing, short gel time, easy resin coloring and slow hardness increase in the curing stage.

(2) curing agent used methyl ethyl ketone peroxide, accelerator with cobalt naphthenate.

(3) Auxiliary materials, including paste, pearl powder, thixotropic agents. Pearl powder is basic lead carbonate hexagonal flaky crystals, which can be arranged in parallel during the forming process to show pearl luster and thixotropic agent is activated dioxide

Silicon, mainly used to prevent no color infiltration.
